Tide Shaper

If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

If Tide Shaper leaves the battlefield before its triggered ability resolves, the target land will not become an Island.

Tide Shaper will get +1/+1 as long as an opponent controls any land with the Island land type, not just ones named Island.

A land that becomes an Island gains "{T}: Add {U}" and loses all other abilities. It loses any other land types, but it doesn't lose any types or supertypes, such as creature, legendary, or snow.
